Strength & Conditioning
The purpose of this study was to investigate the effects of the pre-exhaustion method on the electromyographic activity (temporal and spectral domain) at different intervals of a set of resistance training. Twenty adults with little or no experience in strength training performed two sets of the seated row exercise at 70%1RM until muscular failure, in a randomized order. Surface electrodes were placed over the latissimus dorsi, teres major, biceps brachii, and posterior deltoid muscles of the dominant side. Results showed that the pre-exhaustion did not increase EMG activity of all muscle analyzed at any intervals of a set. Furthermore, the EMG median frequency decreased in teres major and posterior deltoid muscles during initial and intermediate repetitions. Results suggest that the pre-exhaustion induces more fatigue when compared to traditional training.
